Guidelines for the preparation of asset management plans for irrigation infrastructure
Asset management planning is the process of establishing the condition of infrastructure as a basis for evaluating the level of investment required to maintain or enhance its condition and utility. Good management of assets results in increased longevity and sustained utility of the infrastructure and an enhanced level of service provision to the water user. The guidelines provide a framework to apply asset management planning to irrigation infrastructure.
Background
The aim of the study was to assess the potential for adapting and transferring to the irrigation sector the asset management methodology used by the water supply and sewerage industry of England and Wales following privatisation in 1989. Procedures for irrigation systems were formulated and tested in a field trial in Yogyakarta, Indonesia.

The guidelines
The Guidelines provide a framework for those who wish to apply asset management planning to irrigation infrastructure. They are presented in three parts:
Part I sets out the concepts and their origins in the UK Water industry.
Part II describes the application of asset management planning to irrigation and sets out procedures for the production and use of an Asset Management Plan (AMP).
Part III reflects on the benefits of the AMP, how these can be maintained and the practicalities of implementation.

What it covers
The approach to producing an Asset Management Plan is set out as a series of inter-related steps, each of which is outlined and discussed with background information, recommendations and examples or illustrations, wherever possible, from the experiences of the field trial. The steps are:

  • defining systems and function
  • stratified random sampling
  • establishing the environmental, legal and development context
  • assessing system performance - achieved levels of service, how these fit with present and future requirements and what infrastructure adjustments are needed

     

    		•  

  • studying management and operations - a parallel review of the organisation and its procedures
  • doing an asset survey - their extent, value and the liabilities they represent
  • building the Cost Model - analysis of historical Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) as a basis for future projections.

    Intended users
    The intended users include managers of irrigation systems; consultants involved in irrigation system rehabilitation and modernisation, and in advising on maintenance and physical infrastructure management; government agencies responsible for irrigation infrastructure and Water Users Assocoations who have taken over responsibility for the operation and maintenance of irrigation systems.
